To Potty train or not to Potty train that is the question?

This morning Mckenzie had her usual diaper change from waking up. We were putzing in the kitchen or just getting breakfast ready. So we weren't really paying much attention to her. Mckenzie decided she wanted a little freedom, so she took off her diaper and then proceeded to pee on the kitchen floor. She then started to wipe up her mess with the diaper. It cracked us up. Is this a sign that she's ready to potty train? I'm glad it was only pee, anything else could have been really messy:)
